TALKING-MACHINE.

Specification of Letters Patent.

Patented Jan. 1,1918.

Application filed. February 1, 1917. Serial No. 145,876.

To all whom it may concern:

Be it known that I, ADAM A. LONG, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Talking- Machines, of which the following is a specification.

The present invention relates to talking machines and more particularly to a stop mechanism therefor, an object of the invention being to provide an improved construe tion which may be set to stop the machine automatically when the end of the record is reached, such construction being inexpensive to manufacture, simple in operation, and easily adjusted.

To this and other ends, the invent-ion consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Figure 1 is a plan view of a portion of a talking machine with the present improvements attached thereto;

Fig. 2 is a sectional view through the operating parts of the stop mechanism;

Fig. 3 is a detail view of the frictionally mounted releasing element for the brake, such element being shown with the cooperating element projected into its slot for coupling the elements together;

Fig. 4 is a view similar to-Fig. 3, showing the manner in which the cooperatingelee ment engages the frictionally mounted element during the travel of the latter; and

Fig. 5 is a perspective view of the frictionally mounted element and its supporting means.

Referring more particularly to the drawings, 1 indicates the table of the talking machine, which as usual rotates to turn the record 2 so that the reproducer 3 may travel thereover, said reproducer being carried by the tone arm 4 which, in most instances, is mounted to oscillate in a horizontal plane. For stopping the rotary table or part 2, braking means may be employed comprising preferably a lever 4 pivoted at 5 and having a friction surface 6 at one end for cooperation with the flange on the under surface of the rotary table. The other end of this brake lever may be provided with a slot 7 in which a downwardly turned arm 8 of a plunger 9 operates, the plunger 9 being guided longitudinally within a housing 10 and surrounded by a coil spring 11 which acts on the plunger in a direction to throw the lever 4 to a position where the friction device 6 will engage the flange of the rotary table 1. For moving the plunger 9 against the action of the spring 11, a thumb piece 12 may be arranged at the top of the casin 10 and connects with the plunger.

The releasing means for the brake comprises two elements, one connected with the brake and the other connected with the traveling or the oscillatory part of a talking machine. One of these elements is in the form of an extension 13 on the plunger 9 and the other is in the form of a friction-ally mounted element- 14 which is pivoted at 15 to turn about an axisat'an angle to, and preferably perpendicular to, the axis of turning of the oscillatory member or, stated differently, lying parallel to the plane of travel of the oscillatory member 4. This member 14 is provided with a recess or slot 16 extending substantially radially to the turning axis of the member 14 and arranged eccentrically with reference to said axis. This member 14 also has a curved portion 17 to one side of the slot 16 for engagement by the element 13 in the manner to be described.

Any suitable support may be provided for the element 13, that shown comprising an 3 arm 18 carrying the screw 15whichforms the axis of the member 14, said arm being 20 which surrounds the screw 15 but is held against turning on the arm 18 by a pin 21.

In the use of this stop mechanism, the tone arm 4 is turned until the element or device 13 enters the opening 16 so that the elements 13 and 14 are interlocked after which the tone arm is turned until the needle is at the inner end of the record. The member 14 during this movement turns about the axis 15 due to the fact that the member 13 is stationary. When the inner end of the record is reached, the member 13 is withdrawn from the opening 16 and the tone arm is swung to the starting point of the record, carrying the member 14 therewith and causing the member to cooperate with the curved portion 17 of the member 1 1, and the record to turn under the action of its motor. As the reproducing needle is moving over the record, the portion 17 of the member 14 travels over the end of the member 13, until the slot 16 is reached When the member 13 is projected into said slot under the action or" the spring 11, and, at the same time, the brake portion 6 is thrown into contact with the flange of the rotary record supiort thus stopping the machine.

\Vhat I claim as my invention and desire to secure by Letters Patent is:

1. In combination with a rotary part and a traveling part of a talking machine, a brake for the rotary part, and means for controlling the operation of the brake embodying two cooperating elements, one connected to the brake and the other to the traveling part, and one of said elements being frictionally mounted to turn about an axis parallel With the plane of movementof the traveling part.

2. In combination With a rotary part and an oscillatory part of a talking machine, a brake for the rotary part, and means for controlling the operation of the brake embodying two cooperating elements, one connected to the brake and the other frictionally mounted on the oscillatory part to turn about an axis perpendicular to the axis of the oscillatory part, the cooperation between the elements taking place to one side of the axis of the trictionally mounted part.

3. In combination with a rotary part and a traveling part of av talking machine, a brake mechanism for the rotary part, and means for controlling the operation of said brake mechanism comprising a frictionally the traveling part and provided With an opening eccentrically arranged with reference to said axis, and an element controlling the brake, cooperating with the frictionally mounted element to one side of the opening to hold the brake against movement, and movable into the opening to release the brake and to interlock with the frictionally mounted element.

4. In combination with a rotary part, and a traveling part of a talking machine, a brake mechanism for the rotary part, an element movable With the traveling part, mounted to turn about an axis parallel with the path of travel of the traveling part, and provided with an eccentrically arranged recess, and an element connected to the brake and cooperating with the first mentioned element to one side of the opening during a the movement of the traveling part, and movable into said recess to eifect the operation of the brake to stop the rotary part.

5. The combination with a rotary part and a traveling part of a talking machine, a brake for the rotary part, a spring for moving the brake to braking position; a. frictionally mounted element arranged LO move With the traveling part, and to turn thereon about an axis substantially parallel With the plane of the path of travel of said traveling part, said element being provided with a recess to one side of its axis and With a curved portion to one side of the recess, and an element connected to the brake, cooperating With the curved part of the frictionally mounted element during the travel of tl e latter, and adapted to move into said recess to eflect the operation of the brake to stop the rotary part.
